Description

Technical Field

[0001] This invention relates to the field of climbing scaffolding technology, specifically to an intelligent anti-fall buffer prefabricated climbing scaffolding and its lifting control device. Background Technology

[0002] With the rapid development of the construction industry for high-rise and super high-rise buildings, attached lifting scaffolding (referred to as climbing scaffolding) has become a core specialized equipment for building exterior wall construction, thermal insulation coating, and facade renovation due to its advantages such as no need for repeated erection and dismantling, high turnover rate, and low construction cost.

[0003] In existing technologies, intelligent fall-proof buffer prefabricated climbing scaffolds achieve tool-free rapid assembly and disassembly through a modular prefabricated frame structure, adapting to various construction scenarios; coupled with a distributed synchronous servo drive mechanism, it ensures stable and synchronous lifting of the frame; and adopts a dual fall-proof structure of mechanical locking + electromagnetic braking, forming double safety protection.

[0004] However, existing climbing scaffolds are lifted by jacking equipment, and the climbing scaffold itself is limited by a limiting structure. When the jacking equipment lifts the scaffold, it has a lateral impact force. This impact force will hit the limiting structure body. After long-term use, the limiting structure will deform, increasing the gap between it and the climbing scaffold, making the climbing scaffold prone to shaking. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent anti-fall buffer prefabricated climbing scaffold and its lifting control device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent fall-prevention buffer prefabricated climbing scaffold, comprising: The climbing frame has multiple sets of connecting blocks fixed to its surface. A limit plate is fixed to the other end of the connecting blocks. The surface of the limit plate has a groove, and multiple sets of force-bearing rods that bear the thrust are fixed to the inner wall of the groove.

[0007] A lifting control device for the above-mentioned intelligent anti-fall buffer prefabricated climbing scaffold includes a support frame, and a fixing plate that is fixed to the building body is fixed on one end face of the support frame. The surface of the fixing plate is in contact with the surface of the building body to fix the support frame to the surface of the building body.

[0008] Preferably, a limiting frame is fixed to the other end face of the support frame, and the limiting frame has a limiting groove inside for fitting outside the limiting plate, so that the limiting frame can move up and down and slide on the surface of the limiting plate.

[0009] Preferably, the inner cavity of the support frame is hinged to a cylinder via a rotating shaft, and a push head is fixed to the end of the piston rod at one end of the cylinder. As the piston rod moves, the push head can support the bottom of the force rod, thereby driving the force rod and the limiting plate to move upward.

[0010] Preferably, the limiting frame has an extension block integrally formed on the side of the end face away from the support frame. The surface of the extension block has a lifting groove for sliding. The lifting block is slidably inserted into the lifting groove. Limiting strips are fixed on both sides of the lifting block. Limiting grooves are opened on both sides of the lifting groove. The limiting strips are slidably inserted into the limiting grooves. The limiting strips move with the lifting block.

[0011] Preferably, the bottom end face of the lifting block is integrally formed with a connecting plate, the surface of the connecting plate is screwed with a screw rod, and the end face of the connecting plate near the limit frame is screwed with a buffer block for buffering via the screw rod.

[0012] Preferably, the limiting groove is arc-shaped, which allows the lifting block to move away from the inner wall of the lifting groove, and the limiting strips on both sides of the lifting block slide in the limiting groove, causing the lifting block to gradually move away from the inner wall of the lifting groove.

[0013] Preferably, a spring for resetting is connected in the lifting groove, and the other end of the spring is connected to the end face of the lifting block.

[0014] Preferably, the limiting groove is rotatably connected to multiple sets of rollers. The rollers are located on the end face of the limiting groove away from the limiting frame. The rollers can rotate in the limiting groove. As the limiting plate moves up and down in the limiting groove, the rollers rotate in contact with the surface of the limiting plate.

[0015] Preferably, when the limiting plate rests on the surface of the buffer block, the buffer block can move up and down with the limiting plate due to friction. When the limiting plate stops, the buffer block can return to its initial position under the elastic force of the spring.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The fixing plate proposed in this invention is fixed to the surface of the building by screws. The limiting frame is located outside the limiting plate. The limiting plate is connected to the climbing frame. One end of the cylinder drive rod is held against the bottom of the force rod on the slotted surface. The cylinder drives the drive rod to rise, which in turn drives the limiting plate to rise. The climbing frame rises with the limiting plate. When the cylinder drives the drive rod to push the force rod, it will generate a lateral thrust on the limiting plate. A lifting block is inserted into the surface. A buffer block is fixed to the bottom of the lifting block by screws. When the limiting plate is subjected to lateral impact, it first contacts the buffer block, which plays a buffering role. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 6 The present invention provides a technical solution: Example 1: An intelligent fall-prevention buffer prefabricated climbing scaffold, comprising: Climbing frame 1, with multiple sets of connecting blocks 5 fixed on its surface, and a limit plate 3 fixed on the other end face of the connecting block 5. The surface of the limit plate 3 is provided with a slot 2, and multiple sets of force-bearing rods 4 that bear the thrust are fixed on the inner wall of the slot 2.

[0026] Example 2: Based on Example 1, a lifting control device for the above-mentioned intelligent anti-fall buffer prefabricated climbing scaffold includes a support frame 12. A fixing plate 7, which is fixed to the building structure, is fixed to one side of the support frame 12. The surface of the fixing plate 7 is in contact with the surface of the building structure to fix the support frame 12 to the surface of the building structure. A limit frame 6 is fixed to the other end of the support frame 12. An extension block 13 is integrally formed on the side of the limit frame 6 away from the support frame 12. A lifting groove 15 for sliding is opened on the surface of the extension block 13. A lifting block 17 is slidably inserted into the lifting groove 15. The bottom end of the lifting block 17... A connecting plate 18 is integrally formed on the surface of the limiting frame 6. A screw 19 is screwed onto the surface of the connecting plate 18. A buffer block 20 for buffering is screwed onto the end face of the connecting plate 18 near the limiting frame 6 via the screw 19. Limiting strips are fixed on both sides of the lifting block 17. Limiting grooves 16 are opened on both sides of the lifting groove 15. The limiting grooves 16 are arc-shaped, allowing the lifting block 17 to move away from the inner wall of the lifting groove 15. The lifting block 17 is inserted into the surface of the limiting frame 6. A buffer block 20 is fixed to the bottom of the lifting block 17 by a screw. When the limiting plate 3 is subjected to lateral impact, it first contacts the buffer block 20, and the buffer block 20 plays a buffering role.

[0027] The limiting strips on both sides of the lifting block 17 slide in the limiting groove 16, causing the lifting block 17 to gradually move away from the inner wall of the lifting groove 15. A spring 14 for resetting is connected in the lifting groove 15, and the other end of the spring 14 is connected to the end face of the lifting block 17. The limiting strip is slidably inserted in the limiting groove 16 and moves with the lifting block 17. The limiting frame 6 has a limiting groove 10 inside for fitting outside the limiting plate 3. Multiple sets of rollers 21 are rotatably connected inside the limiting groove 10. The rollers 21 are located on the end face of the limiting groove 10 away from the limiting frame 6. The rollers 21 can rotate in the limiting groove 10. As the limiting plate 3 moves up and down in the limiting groove 10, the rollers 21 rotate in contact with the surface of the limiting plate 3. The limiting frame 6 can move away from the inner wall of the lifting groove 15. The surface of the limiting plate 3 moves up and down. The inner cavity of the support frame 12 is hinged to a cylinder 8 via a rotating shaft. A push head 9 is fixed to the end of the piston rod at one end of the cylinder 8. The push head 9 moves with the piston rod and can hold the bottom of the force rod 4, driving the force rod 4 and the limiting plate 3 to move up and down. When the limiting plate 3 holds the surface of the buffer block 20, the buffer block 20 can move up and down with the limiting plate 3 due to friction. When the limiting plate 3 stops, the buffer block 20 can return to its initial position under the elastic force of the spring 14. When the limiting plate 3 rises, the buffer block 20 rises with the limiting plate 3 due to friction. When the lifting block 17 rises, the plug on the surface of the lifting block 17 rises in the limiting groove 16, causing the buffer block 20 to move away from the surface of the limiting plate 3.

[0028] The fixed plate 7 is fixed to the building surface by screws. The limiting frame 6 is located outside the limiting plate 3. The limiting plate 3 is connected to the climbing frame 1. One end of the drive rod of the cylinder 8 is held against the bottom of the force rod 4 on the surface of the slot 2. The cylinder 8 drives the drive rod to rise, which in turn drives the limiting plate 3 to rise. The climbing frame 1 rises with the limiting plate 3. When the cylinder 8 drives the drive rod to push the force rod 4, it will generate a lateral thrust on the limiting plate 3. A lifting block 17 is inserted into the surface of the limiting frame 6. A buffer block 20 is fixed to the bottom of the lifting block 17 by screws. When the limiting plate 3 is subjected to a lateral impact, it first contacts the buffer block 20. The buffer block 20 plays a buffering role. When the limiting plate 3 rises... When the buffer block 20 rises with the limiting plate 3 due to friction, and the lifting block 17 rises, the plug on the surface of the lifting block 17 rises in the limiting groove 16, causing the buffer block 20 to move away from the surface of the limiting plate 3. The buffer block 20 no longer obstructs the rise of the limiting plate 3. In addition, the inner wall of the limiting groove 10 is provided with multiple sets of rollers 21. The limiting plate 3 is held against the surface of the rollers 21, and the rollers 21 can rotate, reducing friction and allowing the limiting plate 3 to rise smoothly in the limiting groove 10. When the limiting plate 3 stops rising, the lifting block 17 can drive the buffer block 20 to fall and return to the initial position under the push of the spring 14 in the lifting groove 15.
